We are seeking an innovative and experienced Senior Mechanical Engineer to lead the design, integration, and validation of mechanical systems and advanced packaging for high-performance computing and communication hardware. This role requires a strong foundation in mechanical design, DFM, and system-level integration, as well as the ability to drive innovation in liquid cooling, IC packaging, and manufacturing processes.

• Mechanical Design: Design and optimize chassis, enclosures, cold plates, and mounting structures for rack-mounted systems, ensuring performance, structural integrity, thermal efficiency, and manufacturability.
• Material Selection: Select materials based on thermal, mechanical, and electrical properties to meet reliability and performance goals.
• Prototyping & Testing: Build and test mechanical and packaging prototypes. Conduct validation testing (thermal cycling, shock, vibration) and iterate on design improvements.
• Cross-Functional Collaboration: Partner with electrical, thermal, and manufacturing engineers to integrate electrical/optical components into product designs and ensure functional compatibility.
• Design for Manufacturing & Root Cause Analysis: Apply DFM principles early in the design cycle. Lead FMEA, conduct root cause investigations, and resolve reliability and yield challenges.
• Documentation & Communication: Develop comprehensive documentation, including specifications, test plans, design reports, and manufacturing drawings. Present designs and findings to technical and non-technical stakeholders.
• Quality Assurance: Ensure compliance with industry standards and implement QA processes throughout the design and development lifecycle.

• Bachelor’s or Master’s degree in Mechanical Engineering, Materials Science, or a related field
• 5+ years of experience in mechanical and packaging design, with a proven track record of bringing products from concept to high-volume production
• Strong knowledge of mechanical design for electronics systems, including chassis, board-level components, and packaging for high-speed electrical and optical interconnects
• Expertise in Design for Manufacturability (DFM), Failure Mode and Effects Analysis (FMEA), and root cause analysis methodologies
• Proficiency in 3D CAD tools such as SolidWorks, Creo, or AutoCAD
• Strong written and verbal communication skills, with the ability to clearly document technical concepts and collaborate across cross-functional teams

• 10+ years of experience in mechanical design and packaging for computing or communication hardware systems
• Familiarity with photonics integration, and substrate-level mechanical design.
• Experience collaborating with ODMs, OSATs, and contract manufacturers to define manufacturing processes and solve DFM challenges
• Demonstrated innovation in mechanical architecture, system packaging, or high-density electronics integration
• Experience with advanced thermal solutions including cold plates, manifolds, and CDUs for liquid cooling is a plus
• Experience in simulation tools such as Ansys Mechanical, Icepak, or Flotherm is a plus
• Experience with quality and statistical analysis tools such as JMP is a plus
